Fsd Hanging When Exiting Games

I was wondering if i am the only one with these problems, running FSD on a J-tagged Xbox360.

Often, when i exit a game i.e different XBLA titles, either by returning to the xbox dash by using the controller or exiting from the main menu of the game, i end up with a black screen..and fsd dosent load up. But i can still activate the on screen menu with the controller.

The other problem is that in 1 out of 10 times the dash dosent boot up when i turn on the xbox..it just hangs in the splash screen..

I am running the newest version of dash launch, and FSD is my standard dash. Im running with an internal HDD, (1gb external HDD, soldered to the xbox motherboard).
